1、金属线槽宽度一般小于200mm，而电缆桥架一般则大于200mm。
2、金属线槽主要用于敷设导线。桥架主要用于敷设电缆。
3、金属线槽就只有一种，一般用热轧钢板制作而成。
4、电缆桥架敷设的时候一般应该考虑其载荷、扰度、填充率等等。
5、金属线槽大致等于草食电缆桥架，知识有一些金属线槽的尺寸要小一些而已。
6、两种敷设方式、在流量不同。

电缆桥架和金属线槽区别：电缆桥架是用来敷设电力电缆和控制电缆的，金属线槽是敷设导线和通讯线缆的。桥架比较大，线槽比较小。桥架拐弯半径比较大，线槽大部分拐直角弯。桥架跨距比较大，线槽比较小；固定、安装方式不同。在有些场所，桥架是没有盖的，线槽几乎全是带盖密闭的。线槽是用来走线的，桥架是用来走电缆的。使用环境不同，线槽往往是不能露天使用，而桥架可以。、希望可以帮到您

10.2.1火灾自动报警系统的传输线路应采用穿金属管、经阻燃处理的硬质塑料管或封闭式线槽保护方式布线。10.2.2消防控制、通信和警报线路采用暗敷设时，宜采用金属管或经阻燃处理的硬质塑料管保护，并应敷设在不燃烧体的结构层内，且保护层厚度不宜小于30mm。当采用明敷设时，应采用金属管或金属线槽保护，并应在金属管或金属线槽上采取防火保护措施。采用经阻燃处理的电缆时，可不穿金属管保护，但应敷设在电缆竖井或吊顶内有防火保护措施的封闭式线槽内。
